For proleptic and sylleptic shoots, long shoots and spurs were distinguished. The total number of long shoots and spurs is the sum of proleptic and sylleptic shoots for these two categories. Within a column, different superscripts indicate significant differences according to the Kolmogorov–Smirnov test (P < 5 %).
